I want to be able to add what ever number has been subtracted from one colum
to another colum.

Example: colum A colum B

210 25
200 35
190 45
250 45
230 65
200 95

When I change the number in colum A to a lower number. I want
it to automatically add to colum B. But if I add to colum A, I want nothing
to happen.
Colum A is our in stock amount. Colum B is total used or sold.
This is probably a simple thing to do, but so far I have not found the
formula, or macro to do it.

I Thank You for any Help you may tell me.

Thank You,

Craig Alan Johnson Sr.

Do I need to change any values to make it work?

My colums are "C" and "I" do I need to ref. them somewhere in the code?

Thank You,

I did finally get it to work. Thank you very much. What if you have colums
spaced every other one? Would a simple change in the program have to be
made, or would it have to be re-written? I am sure you can tell I am new at
this. Thank you for your help!

This will do B,D,F,H,J,L columns

Option Explicit

Private prev As Variant

Private Sub Worksheet_Change(ByVal Target As Range)
Const WS_RANGE As String = "A:M" '<== change to suit

On Error GoTo ws_exit
Application.EnableEvents = False

If Not Intersect(Target, Me.Range(WS_RANGE)) Is Nothing Then
If .Column Mod 2 = 1 Then

With Target

If .Value < prev Then .Offset(0, 1).Value = _
.Offset(0, 1).Value + (prev - .Value)
End With
End If
End If

ws_exit:
Application.EnableEvents = True
End Sub

Private Sub Worksheet_SelectionChange(ByVal Target As Range)
prev = Target.Value
End Sub
